Story: Commission: monetary_nature

monetary_nature is an auxiliary lookup type used by currency to classify whether a currency is fiat, digital, or commodity-backed. It has a SQL table, a full codegen model, and a Qt window — but it has never been formally commissioned.

The purpose of this story is to close that gap: every codegen profile must produce zero drift (or every non-zero delta must be signed off by category and committed as a template fix or code fix), the SQL DDL must satisfy the canonical Domain entity evaluation checklist criteria, the Qt window must be manually verified end-to-end, and the type must be documented within the parent currency chapter.

Process reference: See Entity commissioning process reference for the canonical codegen output map, drift classification rules, and the standard task checklist.

monetary_nature was first analysed as part of Commission: currency. Several codegen sync tasks were executed there for this type:

What has not been done:

• SQL DDL audit against the full checklist
• SQL codegen sync (sql profile)
• Qt UI end-to-end manual verification
• Documentation in the currency chapter

Codegen (all profiles)

• sql profile: zero diff for monetary_nature SQL files, or every delta signed off and committed (template fix / code fix / accept with justification).
• domain profile: zero diff for monetary_nature domain, json_io, table, table_io files (six files), or every delta signed off. Note the known domain secondary template path issue: verify that secondary templates produce files in the correct location (projects/ores.refdata/api/, not an untracked projects/ores.refdata.api/).
• repository, service, generator: zero diff (previously confirmed; re-verify if templates have changed since).
• protocol, nats-eventing, nats-handler: zero diff.
• qt: zero diff (confirmed in PR #1311; re-verify if qt templates change).
• Drift classification table recorded for every non-zero delta.

SQL

• All DB-layer checklist criteria met (see Domain entity evaluation checklist Aux column): temporal columns, GIST exclusion, indexes, insert trigger with security definer + set search_path, validate function with same, bootstrap guard using valid_to filter, soft-delete rule.
• Any gap either fixed inline or filed as a capture.

Qt

• MDI list window loads correctly (records displayed, columns correct).
• Detail dialog: edit a field, save, reopen — change persisted.
• History dialog: after a save, history shows at least two versions.
• Delete: record removed; history entries preserved.
• The type appears correctly as a dropdown in the currency detail dialog.

Documentation

• monetary_nature documented as a subsection of the currency chapter: valid codes + descriptions listed (Fiat, Digital, Commodity-backed, etc.); purpose explained for an operator.
• Site builds cleanly.
• Wt and HTTP gap captures filed (backlog).

• Auxiliary scope. monetary_nature is an auxiliary type: shell and CLI commands are N/A for this entity (operators interact with it only via the Qt dropdown in the currency detail dialog and via codegen-driven list/count/save/delete in the service layer).
• Documentation in parent chapter. Auxiliary types are documented as subsections of the parent entity's manual chapter rather than having their own chapter.

• Implementing standalone shell or CLI commands for monetary_nature (auxiliary type; if needed in future, file a capture).
• Wt and HTTP REST endpoints (file gap captures; out of sprint scope).
